.SH NAME
XFontSetExtents \- XFontSetExtents structure
.SH STRUCTURES
The
.ZN XFontSetExtents
structure contains:
.LP
.Ds 0
typedef struct {
        XRectangle max_ink_extent;      /\&* over all drawable characters */
        XRectangle max_logical_extent;  /\&* over all drawable characters */
} XFontSetExtents;
.De
.LP
The 
.ZN XRectangle
structures used to return font set metrics are the usual Xlib screen-oriented 
rectangles
with x, y giving the upper left corner, and width and height always positive.
.LP
The max_ink_extent member gives the maximum extent, over all drawable characters, of
the rectangles that bound the character glyph image drawn in the
foreground color, relative to a constant origin.
See 
.ZN XmbTextExtents
and
.ZN XwcTextExtents
for detailed semantics.
.LP
The max_logical_extent member gives the maximum extent,
over all drawable characters, of the rectangles 
that specify minimum spacing to other graphical features,
relative to a constant origin.
Other graphical features drawn by the client, for example,
a border surrounding the text, should not intersect this rectangle.
The max_logical_extent member should be used to compute minimum 
interline spacing and the minimum area that must be allowed
in a text field to draw a given number of arbitrary characters.
.LP
Due to context-dependent rendering,
appending a given character to a string may change 
the string's extent by an amount other than that character's
individual extent.
